In outer space, there has been no definit proof that life exists, but there is proof that there was once water on mars, creating the possibility of life.

In extreme heat or cold, there have been bacteria that have been found.

Life has been found just about anywhere on Earth.


What is the likelihood that other forms of intelligent life exist in other forms on other planets?

The likelihood of other forms of intelligent life existing on other planets is difficult to determine definitively. However, given the vastness of the universe with billions of galaxies and planets, many scientists believe it is probable that other forms of intelligent life could exist elsewhere. Ongoing research in astrobiology and the discovery of exoplanets have fueled interest in the search for extraterrestrial life.


Do martians exist why or why not?

Well I don't know about martians but scientists have discovered that the life paterns on mars do indicate that there could have once been small life forms such as bacteria, but there aren't any curent life forms at the moment.


What Scientists all forms of life?

I'm assuming you meant "What scientists study all forms of life?" The answer is biologists (the root word "bio" means "life").


What role does water play in the search for life?

If you consider the concept of life as human beings understand it, water is absolutely necessary for life forms to exist. Life forms on our planet consist primarily of H20. Therefore, scientists will look for places that have abundant water as possible places for life to exist elsewhere. However, there are creatures that live at the bottoms of the oceans that require some type of sulfur in their environment. I'm not sure which type they need. As I recall, the sulfur is used in their 'bodies' the same way most life forms use oxygen to live. Something to do with respiration. I think this was a relatively recent discovery. Before that, scientists assumed that every life form required oxygen to exist. I believe that we limit ourselves in defining the existence of others according to what we ourselves have experienced. This is 'thinking inside the box'. No one seems to consider that life may exist in ways other than what we understand. Other life forms could possibly not be limited by the same factors as the life forms on Earth. Perhaps OTHER conditions are necessary to create different forms of life????

What are some reasons that scientists think living things may have existed?

Scientists have discovered fossil evidence of ancient life forms, such as microbial mats and stromatolites, that suggest life may have existed as early as 3.5 billion years ago. Additionally, organic molecules necessary for life, like amino acids, have been found in meteorites and interstellar clouds, supporting the possibility of life elsewhere in the universe. The discovery of extremophiles thriving in extreme environments on Earth also hints at the potential for life to exist in harsh conditions.


Is it possible for non carbon-based life forms to exist on Earth?

While carbon-based life forms are the most common on Earth, it is theoretically possible for non carbon-based life forms to exist. However, there is currently no evidence of such life forms on our planet.

Why was the discovery of the sulfur-eating bacteria important to scientists' understanding of this unique ocean-floor ecosystem?

Scientists thought that there would be no animal life in a place where there is no energy from the sun. You can go to http://www.yahooanswers.com and search the same question up (if it exists) and they will provide an answer.
